Exclusive: How the Boundary Commission could smash the Tory DUP love in

While everyone has been concentrating on the wrangling between Cabinet ministers over Brexit another crisis is looming for Theresa May which could cause enormous bad blood between the Tories and its newly found friends, the Democratic Unionist Party.

Theresa May has inherited from David Cameron a controversial revamp of all Parliamentary boundaries with the aim of slashing the number of MPs from 650 to 600.

The review is being undertaken by the Boundary Commission- independent of government – but set to strict guidelines on the size of each constituency. A move to reform Parliamentary boundaries collapsed during the coalition government when the Lib Dems voted it down and Cameron and Theresa May backed its revival when the Tories won a majority. The change is expected to benefit the Tories at the expense of Labour because many of the smaller constituencies are inner city seats.

In Northern Ireland the Boundary Commission has made its recommendations are they are extremely bad news for the DUP. The number of seats in Northern Ireland are cut from 18 to 17 – with the loss of one Belfast constituency – but the real controversy is the complete redrawing of all the other seats to meet the new standard size constituency.

As I have written in Tribune this radical revamp means the DUP are set to lose three of its ten seats and Sinn Fein is expected to gain two – making it the largest party from Northern Ireland. The DUP have reacted with fury and complained to the Commission asking them to change the proposals.

Sir Jeffrey Donaldson, MP for Lagan Valley, which will disappear to become part of a new constituency under the changes, said: “The proposals are not welcome. We have made representations to the Boundary Commission to get them changed and expect them to publish their final proposals in September”.

More seriously for the government, the proposals are not part of the deal agreed with the DUP on “confidence and supply”. This was confirmed by Sir Jeffery, meaning that the government could face a defeat in the Commons next year if the DUP decide to vote them down – denting the government’s position still further and possibly triggering a general election before Brexit negotiations are completed.

Such a defeat would cause enormous damage for ministers because it would mean that the next full term general election, originally scheduled for 2020 and but now 2022, will have to be fought on the present boundaries. These are now years out of date.

And the embarrassment will not be confined to N Ireland.There is no provision under the Act which set up the boundary review to allow any special concessions to N Ireland. So not a single Parliamentary boundary will change if it is voted down in the Commons.

The damage by this debacle will only add to the frailty and weakness of this government – if it can survive as long as next year.
